That Fish Blog – Aquarium Advice and Information

Live plants are to the freshwater aquarist what live corals are to the saltwater reef aquarist. They add a natural look to the tank, can benefit the water quality and other livestock and can be a challenge to maintain and “aqua-scape” into just the right look for the aquarium. Just as corals need to be placed in the right area of the aquarium and secured correctly so they can remain healthy and thriving, so also do plants need to be planted correctly and appropriately. Knowing how to best plant different types of live plants that you may have will help them thrive. Keep in mind however that these are general guidelines. Some plants prefer larger or smaller substrates or may have special considerations for their species.

Bunched Plants

Bunched plants are popular and common. Though their appearance, care and requirements vary, “bunched plants” are all sold as bundled individual stem cuttings held together with a metal plant anchor or rubber band.  These plants generally root within a week or two and the growing tips can be pruned and replanted to make new plants. Some bunched plants like hornwort an anacharis, can be left floating on the water’s surface. You can plant each stem of a bunch individually by inserting the end into the substrate, or keep them in their bunches for a bushier look. The plant anchors or rubber bands can be removed once the plant is rooted in place. Read More »

No matter the profession, everyone has favorite parts of their jobs. One of my favorite “duties” is identifying the livestock we get into our store. Although we used to only offer them as “assorted” individuals, we recently started identifying the Mantis Shrimp we get in whenever possible and they’ve become my new favorite subjects!

Mantis shrimp offer some of the most varied coloration of all the marine animals that enter the hobby. The same species can have a seemingly unlimited array of color schemes depending on where they were collected, gender, surrounding habitat, and a number of other factors. Knowing what to look at as the characteristic and consistent traits is key. Sometimes, especially when they are small, it can be difficult to inspect these aspects without getting closer to the shrimp than you may like or without examining a molt or dead shrimp. Many of the available references use rather technical anatomy terms that may not be easy to understand. Here are some terms that are helpful to know and parts of the shrimp that are helpful to look at when trying to identify a mantis shrimp: Read More »

“Why is that snail just sitting there? Is it dead? Why do they keep dying?”

Common questions with a lot of possible answers – Water quality, mineral or vitamin difficiency, starvation, predation – but often the solution can be quite simple…it fell down and couldn’t get up. Snails crawl around all the time, but falling off of a surface and ending up with their shell on the sand can be a death sentence.

Most snails aren’t adapted to environments where there they may get flipped upside-down (like falling off the straight sides of an aquarium). They are from environments where they are either not climbing at all (like sand flats) or where if they do fall, they either roll until they are right-side-up again or fall where they can reach another surface and right themselves. Being upside-down for short periods of time won’t kill the snails, but it does leave them vulnerable to predation from tankmates, and they can’t feed or do any other normal snail things. Some snails can flip themselves over like acrobats, but others may need a hand if they get stuck. Read More »

Outbreaks of nuisance snails are one of the most common problems encountered in planted aquariums. Though much maligned, snails are perfectly normal in tanks with live plants and can even help with algae control. The problems occur when the snails reproduce and become out of control. Throughout our blog posts, we’ve gone over a number of methods of controlling snails through predators and removal methods, but as with any problems, the problem can be avoided with preventative measures.

A common way of cutting down snail populations is to dip new plants, killing snails and snail eggs before they enter your aquarium. We have here a few different “recipes” for these dips. Keep in mind that while these have been used successfully by many aquarists, sensitive plants may still be damaged. You can try your chosen method on one plant before using it on all of your new plants. These are also all solutions that are to be utilized in a separate bucket, tub or sink – NOT in the aquarium!

“Salt Creep” is a very common issue in any aquarium, although it is seen most in saltwater systems. As water evaporates, it leaves behind any minerals and particles suspended in it. Most of the time, we see this as a salty crust on the top of a saltwater aquarium, but freshwater tanks with a high mineral content (high hardness) can have some “creep” as well. Some creep is completely normal in any system, especially higher temperatures, but if you are noticing that the crust builds up quickly or seems out of control? This could be a symptom of Electrolysis – the separation of ions using an electrical current. Read More »
